An independent campaign group supporting presidential candidate Michele Bachmann is taking its message to Iowa TV.

Keep Conservatives United will air a 30-second commercial knocking Bachmann rival Rick Perry on Fox News in the Cedar Rapids media market beginning Thursday, the group announced this morning.

The add zaps Perry, the governor of Texas, for his executive order requiring girls in the state to receive a vaccine against the human papillomavirus, a sexually transmitted disease that can cause cancer.

Bachmann attacked Perry on the order — which was never enforced — in a candidate debate last week.

Here’s the ad:

North Carolina-based Keep Conservatives United is backing Bachmann but under federal law must remain independent of her campaign. This TV spot is its first foray into Iowa, home of the first-in-the-nation presidential caucuses. The group has previously run TV and radio ads in South Carolina, an early primary state.
